Dental history facts
Our cavemen ancestors were dealing with many of the same oral health issues that we deal with today, even if they didn't know how to articulate those problems as well as we do. And recorded dental history goes as far back as 5000 BCE! So let's take a stroll back through time and learn a little bit about the history of dentistry and teeth in general.
- In 5000 BCE one of the first dentists made a note attributing dental decay to ‘tooth worms' in a Sumerian text.
- 2600 BCE marks the death of the world's first (known) dentist. He was named Hesy-Re, an Egyptian native whose tomb reads: “The greatest of those who deal with teeth, and of physicians.”
- From 500–300 BCE Hippocrates and Aristotle dabbled in dentistry, writing about the eruption pattern of teeth, gum disease, tooth extraction and even how to stabilize loose teeth with wires.
Let's jump forward now to the Middle Ages!
- In 700 the Chinese were using amalgam fillings
- The year 1210 sees the establishment of the Guild of Barbers in France. These surgeons specialized in bleeding, tooth extraction and of course, haircuts.
Let's skip ahead to the 18th century, when dentistry as a profession was born:
- In 1723, Pierre Fauchard, the “Father of Modern Dentistry” published “The Surgeon Dentist”, a book that lays out a system for the practice of dentistry including oral anatomy and restorative techniques.
- From 1750–1770 we have the career of the first dentist, Isaac Greenwood, to be born on American soil. Well, technically British-American soil, but not for long!
US dental statistics
And now some general facts about the state of our nation's teeth:
- 15–20% of adults from 33 to 44 years of age have some form of gum disease.
- In adults between the ages of 20 and 64, 91% have dental caries and 27% have untreated tooth decay.
- Untreated tooth decay is higher for Hispanic and non-Hispanic black adults compared with non-Hispanic white and non-Hispanic Asian adults, which says a lot about racial inequality in the field of dentistry.
- Around 50% of Americans visit the dentist every six months, around 15.4% once per year and 11% once every two to three years. More than 21.3% haven't visited a dentist in a few years.
- There are only around seven dentists per 10,000 patients in the US.
- 84% of adults in the US between the ages of 18 and 34 say that bad teeth can negatively impact your life.
- 83% of adults in the US say that their current health-related priority is oral health. This is higher than mental health, exercise, and diet.
- Fewer than 1/3 of adults 65 and older have dental insurance.
Facts about children's teeth in the US
Although there seems to have been a slight decrease in the number of cavities that children in the US have had over the years, experts say that this decline is not statistically significant. Let's have a look at the current state of children's teeth:
- Cavities are one of the most common chronic diseases in kids in the US.
- Children with poor oral health often miss more school and have lower grades than children with good oral health.
- Around 20% of children aged 5 to 11 have at least one untreated decayed tooth.

- Between 15% and 50% of people suffer from bad breath around the world.
Dental hygienist facts

- There are over 150,000 registered dental hygienists in the US.
- 98% of hygienists in the US are women.
- There are 300 entry-level degree programs, 60-degree completion programs, and 18 master's degree dental hygiene programs.

- 50 to 80% of adults in the United States have some dental anxiety.
- More than 20% of dentally anxious patients don't see a dentist regularly.
- 9 to 15% of patients with dental anxiety avoid dental care altogether.
- Dental anxiety is higher when pain has been experienced at previous dental visits.
- In most cases, the earlier you get your kids seeing the dentist regularly, the less dental anxiety they will have.
Wisdom teeth statistics
Despite their association with knowledge, we really don't know a lot of wisdom teeth facts and wisdom teeth removal facts. But here's a look at just a few:
- Wisdom teeth serve no purpose anymore. They were used for chomping into raw meat and roots. But now we eat softer foods, and we cook a lot of what we eat.
- The oldest known case of impacted wisdom teeth is from a woman who died 15,000 years ago.
- Some dentists always recommend the removal of wisdom teeth before there are any problems, while others say removal shouldn't happen unless there's impaction or infection.
Teeth whitening statistics
Chances are you've done it or are at least thinking about it. Teeth whitening is one of the most popular dental procedures. So let's find out more about it:

- 80% of Americans between 18 and 49 want whiter teeth.
- 85% of those are women.
- Americans spent more than $1.4 billion on over-the-counter tooth whitening products last year alone.
Missing teeth statistics
Missing teeth aren't just an aesthetic problem, they also make it more difficult to eat and chew food. And over time, they result in bone loss from your jaw.
- 178 million Americans are missing at least one tooth.
- 40 million Americans are missing all of their teeth!
- 30% of adults between the ages of 65 and 74 years have no natural teeth.

- Dental implants have a success rate of 98%.
- 30% of US general practitioners expect to place implants.
- Immediate-load implants will comprise around 15% of all implant procedures.
- The first dental implants could go back as far as 600 AD. The remains of a Mayan woman from that time was found with tooth-like pieces of shell hammered into her jaw! Ouch!
- Titanium, which is used in dental implants, naturally fuses with bone, which is why these are a permanent solution.
- Just over 3 million people in the US have implants; not many considering they are the best way to replace teeth! Must be due to the high cost of implants, and the lack of federal funding for dental insurance!
- The number of implant patients in the US grows by 500,000 per year.
- Although mini dental implants are considered the best solution in cases when there isn't sufficient bone or gum tissue for standard implants, their use is declining due to the increase in the perception that they don't offer adequate restorative capabilities.
Paying for dental work
- 59% of adults say they don't go to the dentist because of costs. Did you know that universal healthcare could help solve this problem?
- 59% of adults have private dental benefits, 7.4% have Medicaid dental benefits and 33.6% have no dental benefits.
- 38.5% of children have dental benefits through Medicaid or CHIP.
- 35 states including the District of Columbia provide at least limited dental benefits for adults on Medicaid. That's why it's so important to support these programs!
Teeth facts for kids
Get your kids interested in their dental health with these dental fun facts and weird facts about teeth.
- Natural, healthy teeth aren't actually pure white! They are a slightly yellow color. That's because there's a layer of yellow dentin under the outer layer of enamel.
- Some babies are born with teeth showing! And some children don't get their first tooth until after age one.
- Before modern toothbrushes were invented, people used to chew on frayed twigs to clean their teeth.

US vs UK
We all know about the stereotype that British people have bad teeth. But are ours really that much better?
- The average number of missing teeth in a person is higher in the US (7.31) than it is in the UK (6.97)
- This may be because the US has higher levels of economic inequality compared to the UK.
- And that in the UK, you can get dental care from the NHS, whereas in the United States you're lucky if you live in a state with state-funded healthcare that covers dental work. Although, there are many people working to get rid of this program as we speak, well, as you read.
